How you react to this book, which has just been issued as a paper back, will depend on your own individual belief systems. In setting out to read it I felt it appropriate to identify places where the book reinforced my own beliefs and – more importantly – where there is a conflict – and why. As a result what follows is a personal commentary rather than a formal review. In particular it ends with a discussion on theories of how the believing brain works. It also looks at some of the reason why your believing brain might not accept an unconventional evolutionary model which suggests that the human brain is little more than an enlarged animal brain which is only more powerful because it has more neurons, has more synapses, a modified developmental framework and similar straightforward homologous changes.

Hemel (an association of Churches in the Hemel Hempstead
area) has organised a summer family event in
Gadebridge Park. This included an evening debate, held yesterday,
with the challenging title “This House Believes that God is a
Delusion”, to be proposed by Richard Norman, a Vice President of
the British Humanist
Association, with the case against being put by Justin
Thacker, chair of Across Hemel.

The National Trust decided to stop posts on the issue of the Giant's Causeway from appearing on its Press Room blog - and undoubtedly because of the complaints they got about this they restarted them again - but apparently introducing moderation - and then made no arrangements that moderation should be carried out reasonably quickly - which would clearly be essential if the re-opening of the posting facility was meant to be genuine.

Earlier this month the National Trust opens a new Visitors Centre at the Giants Causeway and a storm has broken out over a few words spoken in a display, and the way they have been misquoted by the Young Earth Creationists. I have not seen the exhibit and I am happy to accept that the main display gives an accurate account of the current scientific views of its origins, However there is a listening point where historical voices can be heard discussing historical theories about the origins of the Causeway.

I have read Dennett's article A Perfect and Beautiful Machine with interest and I feel his whole argument is based on a false
premise. Any mathematician knows that there are usually ways of
building alternative mathematical models – and you need to select a
model appropriate to the task in hand. Because Turing's model
explains the success of the stored program computer Dennett makes the
assumption that it must be the appropriate model for understanding
the working of the brain. But let us look at the model Turing started
with, as described by Dennett

“He took human computers as his
model. There they sat at their desks, doing one simple step after
another, checking their work, writing down the intermediate results
instead of relying on their memories, consulting their recipes as
often as they needed, turning what at first might appear a daunting
task into a routine they could almost do in their sleep.”

Come on.Lets be realistic. Several
hundred generations ago we were all hunter gatherers and what is
being describe has absolutely nothing to do with the way the brain
evolved up till then, and there is no evidence that it has changed
significantly in the last 10,000 years or so. A room full of human
computers is a very artificial situation as only some people (not
everyone would be good at it) could carry out out a
highly repetitive and deadly boring task. To do it they have to behave like a zombie (because they could almost do it
in their sleep) to a recipe (because
they cannot be trusted to use their own initiative, so a recipe
“creator” had to tell them what to do). The task
is beyond their brains normal capacity (they
write down information because they cannot trust their memories).
In addition the overall effect of their labour is to carry out a
well-defined and highly formal task which is related to some very
narrow aspect of the culture of their society. Their activity is
totally directed – while the whole point of evolution is that it is
blind to the direction it is going. Put in this way it is hard to see
why anyone should think that Turing's “human computer model” has
anything to do with the environment in which the human brain
evolved.

If we are really honest we must admit
that the task that faced Turing was the design of systems which could
quickly and efficiently carry out highly repetitive computational
tasks, and he was employed to do this because humans could not carry out such tasks in a fast and reliable manner, even when given
extensive training and very precise instructions. The Turing model is
actually an extremely useful and powerful model of what humans cannot
naturally do!!!

It is a year since I have posted
anything about the BBC software on this blog – and during the intervening months
I have thought about the matter frequently – especially as I now
have a BBC computer sitting next to my P.C. and I can switch on the
system, pull out the keyboard and run MicroCODIL without doing more
than swivel my chair through 450.

So read on to find out why I have not yet transferred the software to a PC.

We are having serious problems with our banks. In recent weeks the bank that I use decided to make a change to its computer system, and got it very badly wrong. I was lucky, as I had no transactions going through during the crisis week. On the other hand a very large number of people found that their salary had not been paid, or could not withdraw desperately needed funds. For instance some people had house purchases collapse - leaving them homeless - because their solicitor could not transfer the payment. At least one person spent a weekend locked in a cell because the Court could not cash his bail cheque.

About Me

A.K.A. Hertfordshire Chris -
I am, by temperament, a scientist who likes to stand back and get an overview - rather than getting stuck in a narrow specialist area. I am particularly interested in how people process information and how we could design systems that fit into the way that people think.
Since I retired I have been very much involved in mental health service provision (but have recently retired from all committee work) and I run a web site at www.hertfordshire-genealogy.co.uk which provides help and advice for people whose ancestors lived in Hertfordshire.
